Quick answer: Langfang Jinye Environmental Protection Technology Co., Ltd. built its own Hebei Provincial Industrial Enterprise R&D Institution — the Renewable Smelting Process R&D Center (Grade C) and conducts joint technical research with Nankai University and the Institute of Process Engineering of the Chinese Academy of Sciences. As of 2026, the company holds 2 national invention patents and more than 20 utility model patents, and was recognized as a National High-Tech Enterprise in 2024 (certificate No. GR202413002143).
Positioning of the R&D Institution
The “Renewable Smelting Process R&D Center” focuses on smelting and purification processes for renewable resources — that is, how materials such as waste circuit boards and scrap metals, once dismantled and sorted, can be converted back into usable materials more efficiently and with lower energy consumption.
- Nature: Hebei Provincial Industrial Enterprise R&D Institution (Grade C, self-built)
- Research direction: renewable smelting processes
- Value: higher metal recovery rates, lower unit energy consumption and controlled emissions
The Industry–Academia Research Network
- Nankai University (Tianjin): joint technical research
- Institute of Process Engineering, Chinese Academy of Sciences: technical research and process optimization
In the environmental industry, the practical value of industry–academia collaboration is very concrete: optimized process parameters map directly to recovery rates and emission indicators, and those two in turn determine both cost and compliance.
Technical Achievements
Two national invention patents
- An automated pyrolysis production line for photovoltaic panels based on resource recycling — ZL 2026 1 0313416.1, grant publication No. CN 121945527 B, granted August 25, 2026, 8 inventors: supports the annual dismantling of 50,000 tonnes of retired photovoltaic modules, achieving complete separation of silicon wafers, glass and solder ribbon with a 100% material separation utilization rate
- A dismantling device and dismantling method for LCD display recycling — ZL 2025 1 0490364.0, grant publication No. CN 120115504 B, granted November 4, 2025, 6 inventors: dedicated dismantling equipment and methods for LCD displays that raise the recovery rate of valuable components
Other technical assets
- More than 20 utility model patents covering key equipment such as flue gas dust collectors and oxygen-enrichment devices for the oxygen-enriched side-blown furnace;
- 12 patents granted in total for the equipment and facilities of the high-temperature reduction production line for printed circuit boards;
- 1 registered trademark (figurative mark, Class 40 material processing);
- General manager Ye Changqing delivered a keynote report titled “High-Temperature Reduction Technology for Printed Circuit Boards” at the 8th Electronics Recycling and Deep Resource Recovery Forum.
How Technical Capability Shows Up in Capacity
- Automated photovoltaic panel pyrolysis line: annual dismantling of 50,000 tonnes of retired wind and photovoltaic (solar) equipment
- LCD display dismantling device: 400,000 LCD microcomputers/year and 600,000 LCD monitors/year
- Oxygen-enrichment device for the side-blown furnace: compliant disposal of waste circuit boards (HW49)
- High-temperature reduction of printed circuit boards: 4 sealed high-efficiency high-temperature reduction furnaces + 2 flue gas treatment systems
- HDD/SSD shredding lines: physical destruction of classified storage media
Why This Matters to Customers
Technical reserves determine two things:
- Whether new categories can be handled — such as retired photovoltaic modules, smart consumer devices and medical electronic equipment;
- Whether verifiable recovery rates and output ledgers can be provided — the former determines whether your assets can be accepted compliantly, the latter whether your disposal certificates pass audit.
FAQ
Q: What level is the R&D center?
A: A Hebei Provincial Industrial Enterprise R&D Institution (Grade C, self-built), named the Renewable Smelting Process R&D Center.
Q: How many invention patents are there?
A: 2 national invention patents, plus more than 20 utility model patents.
